PHP - I Am New To Php And Trying To Debug Some Old Code. How Am I To Reade The Follow

Hey folks,
looking for a twitter follow/unfollow php script that WORKS.
any hints/links?
thanks

How can I get robots to follow this mixxed line?:

<td align="left"><?php echo $fieldsFormatted['field_website']; ?></td>

This line outputs the text "Website" with the link to a url depending on row id, but is not followed or index by spiders or crawlers.

Any help is appreciated!

I have a class ServerBridge which is used to proxy browser ajax requests received by a web server to another API server.  To update a record (or create a record is similar):

Browser client makes PUT request to web server. Web server modifies the uri path and passes the body plus headers connection, accept, accept-encoding, accept-language, content-type, content-length only to the API server. The API server does work and returns the location of the resource on itself to the web server. The web server modifies the location header to point to the resource location on itself, and returns all received headers except Date, Server, X-Powered-By, Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers to the browser client. Browser client makes another undesired PUT request to web server.

Why is step 5 occurring and how do I prevent it?  I don't really mind the browser client making another request to the resource, but it would need to be GET and not PUT.  Also, is my white-list headers to forward to api server and black-list headers to return to browser client appropriate?

I haven't posted the ServerBridge script (but can if needed), but did include the requests and headers related to the browser client, web server, and api server below.

Browser client JavaScript

$('.edit-record').simpleEdit('/api/accounts');

jQuery.fn.extend({
    simpleEdit: function(url, options) {
        var dOptions={type: 'text', ajaxOptions: {type: "PUT"}, placement: 'right', send: 'always' };
        options=options?options:{};
        return this.each(function() {
            var $t=$(this);
            var o=Object.assign({
                url: url+'/'+$t.closest('tr').data('id'),
                title: 'Enter '+$t.data('name')
            }, dOptions, options);
            $t.editable(o);

Here  is my hierarchy:

data      -logs folder-debug.log
htdocs   -index.php
include   -Contollers,Smarty,Templater,Zend
templates

Now when I launch index.php from htdocs, I get this un-seeming error:

"Fatal error: Uncaught exception 'Zend_Log_Exception' with message '"/var/htdocs/Books/practical_Web2.0/data/logs/debug.log" cannot be opened with mode "a"' in C:\xampp\php\PEAR\Zend\Log\Writer\Stream.php:69 Stack trace: #0 C:\xampp\htdocs\Books\practical_Web2.0\chapter-02\htdocs\index.php(11): Zend_Log_Writer_Stream->__construct('/var/htdocs/Boo...') #1 {main} thrown in C:\xampp\php\PEAR\Zend\Log\Writer\Stream.php on line 69 "

I went to the zend folder in xampp, php, pear, zend, log, writer.php dir and I found this:

What could be wrong?
Hint:

Any pointer as to why there is a fatal error?

I need help debugging some homework.I have narrowed the problem down to the switch. when it gets to the switch it is spitting out the default everytime, also in the default the $score in both echo statment is not showing. Its probably something small killing me I just can't see it and dont have enough experience with php yet.

I don't know how to debug this.  The if is being executed and I want to have the else be executed.  How can I find out what $_POST['id'] is?

Code: [Select]
if (isset($_POST['id']) === false)
{
echo 'Invalid user id.';
}
else
{
partner_request($_POST['id']);
echo "A request has been sent to the user";
}

Hi all,

Well new to the forum. And New to PHP. I have a quick question.

I'm trying to figure out what the best pratice would be to get familier with a php installation. More specificly how to discover what php is specificly producing a specific part of the final rendered HTML. I have a MyBB Forum me and my cuzin are setting up and for the life of me i can find the right place to add our own HTML to change a specific Div in the Final page output.

here is the link to our URL http://destroyrebuilduntilgodshows.net/forum/ I specificly want to find out where i can edit the contents of the "wrapper_container" Div. I have searched for the source on my local machine. but all i can find is the CSS responsible for the styling and as it turns out the images being held in that div. My end goal is to replace the "advertise here" image with come JS that does our ad managment.


So, I guess my question is How would you find it. How would you find the responsible php for that section of the HTML.



Thanks All.

Cheers

I have a simple INSERT statement that isn't inserting anything into one of the columns: coin_name
I've gone over everything and can't figure out why. All other columns get data.
HTML form passes everything fine. Is there a good way to debug this? I've triple checked everything and there are no type-o's that I see. Driving me mad...


$query = "INSERT INTO Coin (coin_name, coin_value, coin_condition, year_minted, face_value, purchase_price) VALUES 
('$coin_name', '$coin_value', '$coin_condition', '$year_minted', '$face_value', '$purchase_price');";

I'm trying to debug a sporadic 500 error which users occasionally get when filling out form sections on my site. Whenever it happens, I try to recreate their environment and fill out the form exactly as they have done, but can never recreate the issue. I have checked my application logs for the framework I am using, but they report nothing related to the error. I'm hoping someone here might be able to help me catch this. This is where the 500 error is sometimes happening and this triggers the error which users report:

Code: [Select]
//In jquery AJAX function, which submits data to PHP form for processing
error: function(data,transport){
$.validationEngine.debug("error in ajax response: "+data.status+" "+transport)
}
Is there a way for me to try and catch what the exact error is here? The problem is I can't recreate the error, either using an AJAX call or not to call the PHP script. I need to catch the error response from the PHP script being called, but I never get an error when trying to recreate the user issue, i.e same OS/browser/form answers. The Apache error logs for the site have very little - unless I'm looking in the wrong place. I'm on CentOS, ran locate error_log and got an error_log.txt file in my vhosts directory for my site, but this just contained a 302 message log, nothing else. I also tried locate error | grep mysite.

So I have been printing out some debug information, and now I am trying to instead save it to a string, which I will print out at the end of the page. Here is some specific problematic code:

$myplugin_debug_test.= "\n[GETTING COOKIES...\n";
$myplugin_debug_test.= print_r($myplugin_all_cookies);//THIS IS LINE 38
$myplugin_debug_test.= "\n... DONE]<br/>\n";

However, when I do this I get the following error:

Quote

Warning: Cannot modify header information - headers already sent by (output started at ...:38


So my question is how can I output the array data into a string, so that I can print it out later.
Like what am I doing wrong? Is there a better way to do this?

Thanks!

Hi,

I've inherited a website with a problem! Basically the site runs pommo mailing list, which has worked fine for years. Recently though the website domain name changed. Since then - or at least at a similar time - pommo has just stopped working completely. It does nothing but outputs blank pages.

I've never done any php development so I've no idea where to start in terms of debugging this. I've checked that the files etc all exist on the server: they do. I've uploaded a test html page which works. I've uploaded a test php page containing: <?php phpinfo( ); ?> and it works. But when I visit any  page in the pommo application, the browser just renders a totally empty white page - no source HTML at all, just nothing!

Can anyone suggest how to debug this? Even an error message would be somewhere to start.

Thanks all!

I'm a new PHP users needing some help. I've got two code snippets that run a CURL post to a syslog server grabbing specific records that I then parse with regex. Both are similar differing in the specific CURL URL and Regex. One works does not. The failing program seems to fail the regex parse creating a null array. What I've done thus far. Tested the regex on regex101 (works fine, using PCRE). Dumped and echoed the CURL created variable and then rechecked against regex101. ( again all good) Created a static variable in the code of the CURL return string (regex works fine). 

So the CURL is working, the variable string is working appearing as expected and the regex works. But the variable feels like's it null when passed directly from the CURL to the regex. No error logs, but this is where I'm stuck I don't know what to pick at next.  Here's a version of the code. Appreciate any thoughts.

I know a bit about html and javascript, but almost nothing about php.

My question is:

How a can convert this html code into a php file, in order to send a variable value using GET Method and display this variable value inside the javascript code where says VARIABLEVALUE.

Thanks in adavance for your help.

Hi, I have some code which displays my blog post in a foreach loop, and I want to add some social sharing code(FB like button, share on Twitter etc.), but the problem is the way I have my code now, creates 3 instances of the sharing buttons, but if you like one post, all three are liked and any thing you do affects all of the blog post. How can I fix this?


<?php
include ("includes/includes.php");

$blogPosts = GetBlogPosts();

foreach ($blogPosts as $post)
{
echo "<div class='post'>";
echo "<h2>" . $post->title . "</h2>";
echo "<p class='postnote'>" . $post->post . "</p";
echo "<span class='footer'>Posted By: " . $post->author . "</span>";
echo "<span class='footer'>Posted On: " . $post->datePosted . "</span>";
echo "<span class='footer'>Tags: " . $post->tags . "</span>";
echo '
<div class="addthis_toolbox addthis_default_style ">
<a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
<a class="addthis_button_tweet"></a>
<a class="addthis_counter addthis_pill_style"></a>
</div>
<script type="text/javascript">var addthis_config = {"data_track_clickback":true};</script>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=webguync"></script>';

echo "</div>";
}
